0903029 Description

Short technical summary and product information.

The Phoenix Contact 0903029 is an electronic miniature circuit-breaker from the CLIPLINE EC-E... series, designed to selectively protect 24V DC load circuits. It features a solid-state breaker type with an 8A current rating and a 24V voltage rating.

 

This circuit-breaker provides active electronic current limitation for short circuits and an overload shutdown function starting from 1.1 times the nominal current. It can handle capacitive loads up to 20,000 µF, ensuring that loads are only shut down in the event of an overload or short circuit. The device can be reactivated manually via a slide switch or through an electronic reset input.

 

Designed for easy integration, the 0903029 has a compact design width of 12.5 mm and mounts onto NS 35 DIN rails using a modular approach. It is equipped with screw connections for wiring. Signaling of operating and fault states is provided by a multi-color LED and an integrated status output. This component is suitable for applications requiring reliable and fast protection of DC load circuits.
